Explanation:

The aggregate demand is the total goods and services demanded by a country, at a certain price level, in a certain period of time.

The aggregate demand that can be accounted for measures exactly the same as GDP. So they are often used as synonyms.

To calculate aggregate demand, the same methods as for calculating GDP can be used, however, aggregate demand is associated with expenditure, so it is calculated by the product method, that is, from the point of view of what society has spent. This calculation takes into account the expenditure of families (private individuals), what has been spent on investment, the cost of public administrations, and finally, net exports, which is the difference between imports and exports In this way, the Aggregate Demand formula would look like this:

DA = C + I + G + (X-M)
